摘要： Connecting pins in a roller chain are chromized by a diffusion penetration treatment, that results in inner and outer chromium carbide layers on the steel base material. The inner layer contains Cr7C3, and the outermost layer, which is thinner than the inner layer, contains Cr23C6. The surface roughness of the outer layer is reduced by barrel polishing, without removal of all of the Cr23C6-containing layer.

摘要： A transmission chain for a transmission having a drive sprocket and a driven sprocket with chain guides between the sprockets, at least one of the guides having a curved surface on which one of the runs of the chain slides in its travel between the sprockets. The chain has inner and outer link plates which respectively mount bushings and connecting pins which pass through the bushings with a clearance. The link plates have sliding surfaces which slide on the guide. The transmission chain has a chain pitch defined as P1, and the maximum clearance formed between the connecting pins and the bushings is defined as C. The sliding surfaces are curved like the guide and the curved surfaces of one of the outer and inner link plates, has a curve width X, and the curved surface of the other of the inner and outer link plates, has a curve width Y. The widths X and Y are selected relative to the chain pitch of P1 and the maximum clearance C to reduce or eliminate the loss of a film of lubricating oil between the sliding surfaces of the links and the curved surface of the guide as the chain travels from the drive sprocket to the driven sprocket.

摘要： In a roller chain or a rollerless bushing chain, each outer link plate is a gourd-shaped plate having, along the direction of elongation of the chain, a narrow middle portion between two end portions larger than the middle portion. The back height of each outer link plate, is smaller than the back height of each of the inner link plates. The area of each cross-section of each outer link plate, on a section plane perpendicular to the direction of chain elongation and passing through the center of a connecting pin, is at least as large as the area of each cross-section of each inner link plate taken on a section plane perpendicular to the direction of chain elongation and passing through the center of a bushing.

摘要： A method of manufacturing a link plate for a roller chain, and the resulting link plate in which (1) the link plate has a shape comprising a pair of right and left pin holes, a pair of right and left half arcs, which are spaced outwardly from the pin holes respectively, and a pair of upper and lower straight line portions connecting both ends of the pair of right and left half arcs. There are shaved lengths along the pair of upper and lower straight line portions extending into the half arcs, the shaved length extending between the outermost positions of both ends of said pin holes.

摘要： In a roller or bushing chain, inner link plats have an oval shape, with a guide-contacting surface continuous with arc-shaped ends, and in the form of an arc having end points that are spaced from each other by a distance greater than the chain pitch but less than the greatest distance between parts of bushing holes in the inner link plates. The outer link plates have straight parallel edges parallel to the direction of chain elongation and semicircular ends continuous with the straight edges. The configuration of the inner link plates prevents the outer link plates from coming into contact with a chain guide.

摘要： In a transmission chain having link plates with convex edges for sliding contact with a guide surface, the plates are asymmetric in shape so that the distance from a line connecting the centers of the connecting holes and the convex edge is greatest at a position other than at the midpoint between the connecting holes. A pivoting action of the link plates takes place as they slide over a guide surface, changing the abutment point.
